Abstract: An oxygen concentrator is utilized in combination with a compressor to provi de a highly enriched and compressed oxygen gas in a mobile container such as a gas cylinder, The combination and method of production provides for the facile preparation of an enriched source of oxygen for use by an ambulatory or wheelchair-confined patient. Th e oxygen concentrator utilizes two or more molecular sieves to provide a breathable gas of from approximately 80 to about 98 percent oxygen from atmospheric air. The oxygen-enriched gas is stored in a concentrator product tank and can be prioritized so as to supply a patient with a proper amount and concentration of oxygen and secondarily to supply any surplus or excess enriched oxygen to a compressor. The compressor utilizes multiple stages to produce the highly compressed oxygen-enriched gas and utilizes a two-part piston at low rpm to enhance low wear and low noise. The multiple pistons of the compressor can either all rotate at one RPM or in an alternative embodiment, at least a first piston can rotate at a higher RPM than any remaining pistons. Desirably, at least the initial piston of the alternative embodiment is driven by one drive shaft source with one or more other remaining pistons being driven by a second drive shaft.

Filed: 1998-01-06
Granted: 2008-01-08
Abstract: A sensor system (10) preferably for use in a vehicle airbag deployment sys-tem employs spatial shading techniques and centroiding analysis to calculate an equiv-alent point load in two-dimensional space.  The location of the equivalent point load, as well as the weight of the passenger as deter-mined from the sensors (S1-S6), are used to construct a set of fuzzy set logic bound-aries defining different modes of deploy-ing the airbag. The fuzzy set logic bound-aries may include a full deployment, soft deployment, no deployment and other in-termediate deployment zones. In the event of a vehicle airbag incident, the airbag is deployed in accordance with the fuzzy set logic boundary in which the weight and equivalent point load of the vehicle occu-pant are located.

Title: Gas filter separator/coalescer and multi-stage vessel
Inventor: VON PHUL STEPHEN A
IPC: B01D50/00
Filed: 1998-02-02
Granted: 2004-01-27
Abstract: The present invention relates to an apparatus for separating liquids and solids from a gas stream and simultaneously coalescing liquids from the gas stream. The apparatus includes a closed vessel having a longitudinally extending length, an initially open interior, an input port at an extent and an output port at an opposite extent thereof. There is a partition located within the vessel interior that divides the vessel interior into a first stage and a second stage. There is at least one opening in the partition. A separator/coalescer filter element is disposed within the vessel to sealingly extend from within the first stage through the opening into the second stage. There is a chevron-type seal or an O-ring seal between the filter element and the opening. The input port, vessel interior, separator/coalescer filter element and output port together define a flow passage within the apparatus, whereby the gas stream flows into the first stage through the input port and through the filter element hollow core, thereby filtering solids out of the gas stream, separating liquids from the gas stream, and pre-coalescing liquids in the gas stream. The gas stream then flows along the hollow core past the partition and back through the filter element into the second stage, thereby coalescing liquids out of the gas stream, the gas stream then exiting the second stage through the outlet port.

Abstract: A system and method for safely and economically providing up to 1800 watts to downhole equipment is shown in the figure. In one embodiment, the system uses a standard multiconductor logging cable (20) which supports orthogonal signal transmission modes on circumferentially spaced insulated conductors (1, 2, 3, 6, 7). A high-powered power source on the surface (Ml, M2. M3, M4) is coupled to the insulated conductors in the cable to drive a power signal on the lowest impedance signal transmission mode. Safety may be enhanced by the addition of a reliable current imbalance detector configured to shut down all power source when currents in the insulated conductors do not add to zero. The system may further include multiple power sources operating on different independent signal transmission modes, and may also include multiple telemetry channels which share the power transmission modes via multiplexing.

Title: Distributed digital rule processor for single system image on a clustered network and method
Inventor: HART EDWARD F
IPC: G06F9/44
Filed: 2000-03-17
Granted: 2008-12-23
Abstract: A distributed digital rule processor to create a single system image (SSI) o n a cluster of von Neumann processors. The rule processing engine has a group of digital rule nets each having their own local bindery (500) and local controllers (200) which are interconnected by a global bindery (400). Slave translators are interfaced to the global bindery (400) to receive rule calls from the rule nets and return statuses. A compiler maps the typical source code instructions into groups of rules which are stored in the rule nets' storage area (100). The rules contain groups of input variables and output variables. The output variables of a calling rule become the input and data for the called rule. Slave application processes on the von Neumann processors perform slave activities for the slave translators, as the rule nets are unable to manipulate data.
